摘要
The present invention relates to a label submitted to a magneto-elastic excitation, for use in monitoring and identification systems. The inventive label is comprised of a semi-solid magnetic tape for desactivation and, preferably, an amorphous tape acting as a resonator. Said resonator is fixed by one side and the harmonic vibration is stimulated using a quarter of a frequency.
